SonLVL is a level editor for disassemblies of Sonic 1, Sonic 2, Sonic CD and Sonic 3 & Knuckles (additionally supporting S&K Collection and Sonic CD PC). It is designed based on Visual Studio, for people that don't like SonED2's interface. It uses art and mappings data from the disassembly to display objects more accurately than SonED2 can.

Oh wow, that's awesome! Tell me though, will it load seperate files (layout and such) similar to how you load certain aspects in SonMapEd, a file with file locations akin to SonED2, or something different from either of these?

FeliciaVal: I don't know about that (the other Tech Members have been completely unhelpful in that regard), but it's certainly different. The only keyboard controls are moving the camera, and delete to delete objects.

MainMemory, is the Sonic 1 editing program going to work with the .sep project files? Because this is looks more fantastic than SonED2 and with those annoying '?' symbols which make me place objects without some pixel precision.

No. It will use INI files, like S2LVL (and everything else I make). Converting .sep files to INI is rather trivial, if you REALLY want it, I could make a program to convert them. Of course, if you haven't edited the .sep files at all, then the default INIs will work just fine.

I wasn't expecting this many replies, given how none of the techies seemed to care.
